FXO Trunks on Openvox Analog Card

FreePBX Installation / Upgrade
1

I downloaded and installed FreePBX 2.9 and Asterisk 1.8. Both are up and running and I can make calls between extension with no issues.

I have a Openvox A400 card installed in the machine with 1 FXO module in slot 1 and 3 FXS modules in slots 2-4.

When I run dahdi show channels from the Asterisk CLI, I get the following.

Chan Extension Context Language MOH Interpret Blocked State
pseudo default default

When I run dahdi show status, I get the following.

Description Alarms IRQ bpviol CRC Fra Codi Options LBO
Wildcard TDM400P REV E/F Board 5 OK 0 0 0

I can not make or receive calls, but I am not sure how to rectify the issue.

I followed the prompts on the install screens.

I searched the internet looking for answer to my issue, but could not find anything. Not sure if I searched correctly.

I believe it is a device driver issue.

Thanks

Paul

Did you stop asterisk and run dahdigenconf ?

What is in your /etc/dahdi/system.conf and /etc/asterisk/chan_dahdi.conf?

I did stop asterisk. I tired to run dahdigenconf, from the and from /etc/dahdi each time it says command not found. As for what is in the /ect/dahdi/system.conf and /etc/asterisk/chan_dahdi.conf, I don not know how to list or view them.

It’s dahdi_genconf

Did you read the DAHDI getting started guide or the driver installation guide from Openvox?

If you don’t know how to look at or edit a file in Linux you are going to be very frustrated trying to adminster a Linux based phone system. If it helps to display a file use the cat command, nano is also a simple editor that is very popular. vi and joe work well also. vi has a steep learning curve.

Assuming for the moment that the install process for a clone card is the same as real one…

From the command line I would do a yum list dahdi* and make sure you see dahdi-tools.i686 installed, then…

amportal stop

dahdi_genconf

followed by

dahdi_cfg -vv

And then amportal restart. After which you should be able to run "asterisk -rx “dahdi show channels” and see:

Chan Extension Context Language MOH Interpret
pseudo default default
1 from-internal en default
3 from-internal en default
4 from-pstn en default

or what have you.

The command is actually dahdi_genconf -v -F to run verbosely and generate the FreePBX includes.

Which is vastly superior to dahdigenconf… :slight_smile:
